Grant it, the days are long past me.  Racing on the freeway is one of the safer places if done right due to the surface and space outside of a race track.  The guys in the video did not block off the freeway and that was their big mistake.  They could have had a few guys dress up as construction workers in city vehicles and force traffic to an off ramp or had 4 cars block the road with their flashers on.  If you wreck in a rural two lane road, its bad news and usually DOA.  At the end of the night, a bunch of people will face charges and anyone driving a modified car in Tampa for the next 4-6 months will get harassed.  So everyone loses due to a video on youtube.
